Specification of Letters Patent.

Patented Oct. 3, 1913.

Application filed May 11, 1916. Serial No. 96,813.

To all whom it may concern:

Be it known that I, WVARREN A. FARMER, a citizen of the United States, and a resident of Arcade, in the county of Wyoming and State of New York, have invented a new and Improved Silo-Roof, of which the following is a full, clear, and exact descrlptlon.

The prime object of my invention 1s to allow the charging of the silo with ensilage to a height sufliciently above the top of the silo proper to allow for settllng and to produce a full silo of settled ensilage with one charging of material.

In carrying out my invention, use s made of swinging side sections in forming the roof, said sections being provided with depending end members movable with the roof sections relatively to fixed gables on the silo at the roof. I provide means whereby the swinging roof sections may be opened or closed from the ground.

Other objects and advantages of my 1nvention will appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of thls specification in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is an end view of my improyed roof, the swinging roof sections being closed; Fig. 2 is a similar view with the roof sections swung to the open posit on; Fig; 3 is a longitudinal section; Fig. 4. 1s a broken plan view with the parts in the posltion shown in Fig. 2.

The silo body 10 may have any approved structure and usually will be round as shown. On the top of the silo body 10, a super-structure is erected including plates 11, extending in rectangular form. On two opposite plates 11 are built fixed gables 12.

The numeral 13 in Figs. 1 and 2 represents a door in a gable, and the numeral 14 represents a ridge extending between the gables. The ridge 1 1 is, in practice, braced by diagonal braces 15 diverging from said ridge to opposite plates 11 in the vert1cal plane with the said ridge. At the ntersections of the plates 11 outside of the sllo body 10, braces 16 are provided and the angles formed between the ends of the plates 11 and the exterior of the round body 10 are closed by boards 17 or equivalent closing means.

The opposite side sections 18 of the roof are hinged at their lower ends to the plates 11 by hinges 18 so that the said roof sections may swing from the closed position agalnst the ridge 14c and gables 12 to the open position. of Fig. 2; On each swinging roof side section 18 and rigid therewith, I 1

provide at the ends of said section depending members or flanges 19 rigid with the roof sections and of generally triangular form and disposed at the inner sides of the gables 12.v The flanges 19, it is to be observed, are, in the same plane. parallel with the gables 12 to lie close to the gables, whereby to prevent obstruction by the ensilage in the inward swinging movements of the roof sections. The flanges therefore are of a size to be accommodated in the lowered position without overlapping for which reasonthey terminate short of the upper ends of the respective roof sections, the said upper endsbeing continued beyond the flanges to engage the ridge 1a. Thus, the said flanges 19 in the closed position of the roof sections will lie at the inner sides of the gables and when said roof sections are swung outwardly, the said flanges will close the angles between the roof sections and the gables 12, thereby permitting the opensuper-structure to be charged with material approximately to the height of the ridge or to such other height as will provide a quantity of ensilage above the body 10 sufficient to result in a full body'lO when the ensilage has settled.

To swing the roof sections, links 20 are pivoted at their outer ends to the roof sections as at 21 and the meeting ends of said links are pivoted as at 23 to a yoke-like fit ting 22 which, preferably, presents an. oblong loop form, through opposite sides of which the pivots 23 extend.

It will be observed from Figs. 3 and 4, that the ridge 14: and the swinging roof sections 18, extend at both ends beyond the gables 12, and the links 20 are disposed out side of said gables. Wires or cables 24 connecting with the yokes 22, at the top, extend upwardly and over standing sheaves 25 hung on the projecting ends of the ridge 14:, said wires or gables thence extending, in practice, ground or to a point to be reached from the ground. Thus, a pull on the cables 2 L will raise the yokes 22 and the inner ends of the links 20, thereby forcing out the roof sections 18 to the open position. To each yoke 22, below the pivot 23, a second wire or cable 26 is connected and hangs therefrom so that a downward pull on the said downward from the pulleys to the super-structure and having cables 25 will draw the roof sections inwardly and snugly to the gables l2 and ridge 1%. Tie chains 27 extend from the ridge to the roof sections to limit the outward movement of the latter. Latches 28 or other approved fastening means may be provided for securing the roof sections in the closed position.

Having thus described my invention I claim as new, and desire to secure by Letters Patent:

1. A super-structure for silos and the like, includin fixed gables, a ridge extending between said gables and projecting at the ends beyond the same, roof sections hinged at their lower ends to the base of the said depending flange members at the ends thereof swingable with the roof sections and adapted tooform clo= sures of the angles formed by the gables and root sections, when the latter are open, links outside of each gable and pivotally connected at their outer ends with said roof sections, the inner ends of the links at the respective ends of the roof sections being pivoted to each other, cables, means connecting the cables with the inner ends of the links, and guide sheaves suspended from the ends of the ridge and over which said cables run.

A super-structure for silos and the like, including fixed gables, a ridge extending between said gables and projecting at the ends beyond the same, roof sections hinged at their lower ends to the base of the said super-structure and having depending flange members at the ends thereof swingable with the roof sections and adapted to form 010- sures of the angles formed by the gables and roof sections, when the latter are open, links outside of each gable and pivotally connected at their outer ends With said roof sections, yokes to which the inner ends of the said links are pivotally connected, cables connected with the said yokes above the pivots of the links, sheaves over which said cables run, and cables connected with the said yokes below the pivots of the links.
